ASP.Net | Display recent unique visitor number | Neha Sharma

To get the recent user number in ASP.Net using c# follow the below steps:

1.  We need to add a Global.asax page, Global.asax is a page containg session level and application level events, this is also called an application file.

Write the below code in to your Global.asax page:

<%@ Application Language="C#" %>

<script runat="server">

    public static int u_count = 0;

    void Application_Start(object sender, EventArgs e)

    {

        // Code that runs on application startup

        Application["user_Count"] = u_count;

    }

   

    void Application_End(object sender, EventArgs e)

    {

        //  Code that runs on application shutdown

    }

       

    void Application_Error(object sender, EventArgs e)

    {

        // Code that runs when an unhandled error occurs

    }

    void Session_Start(object sender, EventArgs e)

    {

        // Code that runs when a new session is started

        u_count = Convert.ToInt32(Application["user_Count"]); Application["user_Count"] = u_count + 1;

    }

    void Session_End(object sender, EventArgs e)

    {

        // Code that runs when a session ends.

        // Note: The Session_End event is raised only when the sessionstate mode

        // is set to InProc in the Web.config file. If session mode is set to StateServer

        // or SQLServer, the event is not raised.

       

    }

   

      

</script>

In above code “u_count “ ll start from zero but as it goes on the “user_count” and “u_count” ll increase one and ll hold the value “1”.

    2.  Write the below code in to code behind page or .cs file :

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Globalization;

public partial class Default2 : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

        int a;

        a = Convert.ToInt32((Application["user_Count"]));

        Label1.Text = Convert.ToString(a);

        if (a < 10)

            Label1.Text = "000" + Label1.Text;

        else if (a < 100)

            Label1.Text = "00" + Label1.Text;

        else if (a < 1000)

            Label1.Text = "0" + Label1.Text;

      

    }

}
